S-93406A314 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Superior load distribution through the wide truss head design, preventing pull-through in thin sheet metal materials
• Reliable thread forming capability creates strong, permanent threads in sheet metal without pre-tapping requirements
• Enhanced driving stability with No. 3 Phillips drive, reducing cam-out and ensuring secure installation
• Maximum material engagement through full threading along the 3/4" length, providing consistent holding power
• Optimized thread design with 0.242" diameter and 10 TPI for secure fastening in sheet metal up to 0.025" thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These 316 stainless steel Phillips truss head tapping screws deliver critical engineering advantages in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The wide truss head profile provides substantial bearing surface, distributing clamping force effectively across thin materials to prevent deformation and maintain structural integrity. Manufactured from premium 316 stainless steel, these A/AB type tapping screws offer superior resistance to chemicals, saltwater, and industrial atmospheres, making them ideal for HVAC systems, electrical enclosures, marine equipment, and food processing machinery where corrosion resistance is paramount. The combination of fully threaded shank and precise 0.242" thread diameter ensures maximum thread engagement for secure, long-lasting fastening performance.

Specification Summary & Compliance

These No. 14 sheet metal screws feature precise dimensional specifications including 0.242" thread diameter with 10 threads per inch and 3/4" length with full threading. The truss head design measures 0.557" in diameter with 0.146" height, accommodating No. 3 Phillips drive for secure installation. Manufactured as thread forming tapping screws type A/AB with right-hand threading, these fasteners are engineered for use with 5.5 mm (0.2165") drill bits in materials up to 0.025" thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and industrial suitability.
